Scientific paper

Measurements carried out by the incoherent scatter radar at Chatanika, AK were combined with S3-2 satellite data to study the electrodynamics of the midnight ionosphere. The radar measured electric fields and conductivities as a function of latitude and local time and the satellite measured the latitudinal distribution of electric fields and field-aligned current during three polar passes. It was found that dominant field-aligned current in the midnight sector had an upward orientation. Equatorward of the field-aligned current a downward sheet was observed marking the eastern edge of the evening sector region 2 sheet. Poleward of the upward current several sheets associated with active aurora during substorms were found. The most intense electric fields were located at the poleward and equatorward boundaries of the upward current sheet. A model is constructed to demonstrate the self-consistency of the relationships between the conductivities, electric fields, and currents.
